With Xbox on Windows 10, we’re bringing some of the most exciting features from Xbox Live and some of the most popular Xbox experiences into Windows 10 itself. The built-in Xbox app is the place where your world of gaming comes together. It’s a unified view of the games you care about, your friends, and your gaming activities. And with Xbox Live, more than 50 million members will now connect across screens in new ways.

“Over the last 13 years, Xbox has been focused on creating and expanding great gaming and entertainment experiences on console. We’re incredibly proud of the Xbox One and are fully committed to ensuring it’s the best place to play console games in 2015 and beyond,” said Spencer. “Now, we are also bringing that same focus, passion, and commitment to gaming on Windows 10, enhancing the PC games and gaming devices you already love, including the Xbox One. We’ve listened and learned from our past efforts in PC gaming and I am excited about what the future holds.”

Microsoft revealed that a free upgrade for Windows 10 will be made available to customers running Windows 7, Windows 8.1, and Windows Phone 8.1 who upgrade in the first year after launch.

This is more than a one-time upgrade: once a Windows device is upgraded to Windows 10, we will continue to keep it current for the supported lifetime of the device – at no cost. With Windows 10, the experience will evolve and get even better over time. We’ll deliver new features when they’re ready, not waiting for the next major release. We think of Windows as a Service – in fact, one could reasonably think of Windows in the next couple of years as one of the largest Internet services on the planet.

And just like any Internet service, the idea of asking “What version are you on?” will cease to make sense – which is great news for our Windows developers. With universal Windows apps that work across the entire device family, developers can build one app that targets the broadest range of devices – including the PC, tablet, phone, Xbox, the Internet of Things, and more.

For our enterprise customers, we’ll continue to support the way many of them work today, with long-term servicing for their mission critical environments. With Windows 10, a best practice we recommend for many enterprise devices is to connect to Windows Update and be kept up-to-date with the latest security and productivity improvements as soon as they are available. You can learn more about our commitment to enterprises here, with much more to come in the following months.

Everything about Windows 10 – the experiences, delivering it as a service and the free upgrade – means ongoing value to all our customers. The new generation of Windows is a commitment—a commitment to liberate people from technology and enable them to do great things.

Together with our Windows Insiders, we’re well way on our way to making Windows 10 the largest-ever open collaborative development effort Microsoft has ever shipped. Since we launched the Windows Insider Program in September, we’ve been joined by 1.7 million Windows Insiders, who have delivered over 800,000 pieces of feedback. We are truly co-creating the future of Windows with you and we’re humbled by your valuable role in this new open development process.

Windows 10 details:

• Cortana, Microsoft’s personal digital assistant, comes to PC and tablet, for the first time with Windows 10. Cortana learns your preferences to provide relevant recommendations, fast access to information, and important reminders. Interaction is natural and easy via talking or typing, with advanced features to control Cortana for more trustworthiness and transparency.
• Windows 10 for phones and tablets – Windows 10 for phones and small tablets features a fast, fluid and familiar experience that seamlessly interacts with your PC.
• A new web experience for Windows 10 – Code-named “Project Spartan,” the next generation browser was built with greater interoperability, reliability and discoverability, with a new look and feel built just for Windows 10. Advanced features include the ability to annotate by keyboard or pen directly on the webpage and easily share with friends, a reading view that is distraction free, displaying the article in a simplified layout for a great reading experience for Web articles online and offline, and the integration of Cortana for finding and doing things online faster.
• Office universal apps on Windows 10 offer a consistent, touch-first experience across phone, tablet and PC with new versions of Word, Excel, PowerPoint, OneNote and Outlook. Designed from the ground up to run on Windows, you can easily create and edit Word documents, annotate slides in real-time with new inking features or easily present PowerPoint presentations, and with new touch-first controls in Excel you can create or update spreadsheets without a keyboard or mouse. The next version of the Office desktop suite is also currently in development, more on this in the coming months.
• New universal applications will ship with Windows 10, offering innovative new experience applications, consistent across the device continuum, for Photos, Videos, Music, Maps, People & Messaging, and Mail & Calendar. These built-in apps have an updated design that look and feel the same from app to app and device to device.  Content is stored and synced through OneDrive, enabling you to start something on one device and continue it on another.
• Xbox Live and the new Xbox App bring new game experiences to Windows 10. Xbox on Windows 10 lets gamers access the best of the expansive Xbox Live gaming network on both Windows 10 PCs and Xbox One. Players can capture, edit and share their greatest gaming moments with Game DVR, and play new games with friends across devices. Games developed for DirectX 12 in Windows 10 will see improvements in speed, efficiency and graphics capability. Players will also be able to play games on their PC, streamed directly from their Xbox One consoles to their Windows 10 tablets or PCs, within their home.
• Continuum Mode:  On 2in1 devices, Windows 10 will move easily between keyboard/mouse and touch/tablet as it detects the transition and conveniently switches to the new mode.

But it’s not enough to deliver great software experiences. Windows 10 supports the broadest device family ever – from PCs, tablets and 2-in-1s to phones to Xbox and the Internet of Things. And today, we welcomed two new devices to the Windows 10 family: Microsoft Surface Hub and Microsoft HoloLens.

It was a special moment this morning when we were able to share that Windows 10 is the world’s first holographic computing platform – complete with a set of APIs that enable developers to create holographic experiences in the real world. With Windows 10, holograms are Windows universal apps and Windows universal apps can work as holograms, making it possible to place three-dimensional holograms in the world around you to communicate, create and explore in a manner that is far more personal and human.

Showcasing the possibilities of holograms in Windows 10, Microsoft HoloLens is the world’s first untethered holographic computer – no wires, phones or connection to a PC needed. Microsoft HoloLens allows you to view holograms in high definition and hear them in surround sound, even if they are behind you. And with advanced sensors, Microsoft HoloLens can see what you are looking at and understand what you are communicating with your hands and voice.  By putting you at the center of the Windows 10 computing experience, Microsoft HoloLens allows you to create, access information, enjoy entertainment, and communicate in new and exciting ways.

From no screen to 84”, with Microsoft Surface Hub we introduced a new large screen device designed for the way teams in the workplace naturally interact and come together.  Custom versions of Skype for Business and OneNote are integrated into the Windows 10 shell to take full advantage of the built in cameras, sensors and mics, as well as the new screen that was built from the ground up for ink and touch. The Surface Hub features state of the art digital white boarding, instant remote conferencing, the ability for multiple people to share and edit content on the screen from any device, and a trusted platform for large-screen apps. Available in two sizes – 55” and 84” – the Surface Hub removes the current limitations of traditional conference room scenarios to empower teams to create their best work together.
